Fact sheet intended for being inserted between two pages of a stationery product, such as a notebook

Abstract

A fact sheet for insertion between two pages of a notebook, the notebook pages being bound by a spiral binding. The fact sheet includes a sheet having two generally parallel sides and, along one of the sides, a row of perforations into which the coils of the binding can be inserted to removably secure the sheet to the coils. The row of perforations includes a uniform alternation of oblong perforations and narrower perforations that are narrower than the oblong perforations. The alternation has a period including an oblong perforation and a narrower perforation, which are adjacent and consecutive. Each oblong perforation is shaped to receive either one coil or two coils, depending on the separation of the coils of the stationery product, and each narrow perforation is shaped to receive a single coil.

1 . A fact sheet for insertion between two pages of a stationery product, wherein the two pages are bound by a spiral binding with coils, the fact sheet comprising
 a sheet having two generally parallel sides, and   along one of the sides, a row of perforations into which the coils of the binding can be inserted, removably securing the sheet to the coils, wherein
 the row of perforations includes, in alternation, oblong perforations and narrower perforations that are narrower than the oblong perforations, 
 the alternation is periodic with oblong perforations and narrower perforations adjacent to each other, and consecutively arranged, and 
 each oblong perforation is shaped to receive either one coil or two coils, depending on the separation of the coils, and each narrower perforation is shaped to receive a single coil. 
   
     
     
         2 . The fact sheet according to  claim 1 , wherein
 each oblong and narrower perforation comprises a coil-receiving opening and an elastically deformable coil passage neck for engaging and disengaging the sheet with respect to the binding,   each passage neck has a width smaller than a longitudinal dimension of the corresponding opening, and   the passage necks for the oblong perforations are wider than the passage necks of the narrower perforations.   
     
     
         3 . The fact sheet according to  claim 2 , wherein
 each passage neck is defined by two lips that are opposite one another, and   the lips are elastically deformable for deformation during insertion and removal of the coils of the binding through the passage necks.   
     
     
         4 . The fact sheet according to  claim 1 , wherein the oblong perforations and the narrower perforations are periodically separated by a distance substantially corresponding to periodic separation of the coils of the binding, and
 the binding has two coils per period or three coils per period.   
     
     
         5 . The fact sheet according to  claim 2 , wherein
 the openings of the narrower perforations have a circular contour, and   the oblong perforations have circular end contours, a straight bottom contours, and a spiral passage neck opposite the straight bottom contours.   
     
     
         6 . The fact sheet according to  claim 1 , wherein the sheet has a weight in a range from 150 grams per square meter to 250 grams per square meter. 
     
     
         7 . The fact sheet according to  claim 1 , wherein the sheet is selected from the group consisting of paperboard, plastic laminated paper, and a polymer. 
     
     
         8 . A stationery product with pages bound to one another by a spiral binding having coils, and at least one fact sheet according to  claim 1  that can be removably fastened onto the coils of the binding in any location between two pages of the stationery product.
